次に実施例の作用を述べる。 Then describe the operation of the embodiment.
(上下調節) (Vertical adjustment)
ヘッドレスト3内に電気部品5を設け、電気部品5に接続したヘッドレスト内接続コード6の端部をピラー8のピラー側コネクタ10のピラー側金属端子11に接続して、ヘッドレスト3を組立てる。 The electrical component 5 provided in the headrest 3, and connect the ends of the headrest in connection cord 6 connected to the electrical components 5 on the pillar side metal terminal 11 of the pillar-side connector 10 of the pillar 8, assembling the headrest 3.
ピラー側コネクタ10は、絶縁ケース12の係合溝12aをピラー8の係合部13に係合させて、取付けているから、ピラー側コネクタ10はピラー8と一体となる。 Pillar-side connector 10 is engaged with the engaging groove 12a of the insulating case 12 with the engaging portion 13 of the pillar 8, because they mount, pillar-side connector 10 is integral with the pillar 8.

ヘッドレスト3のピラー8を装着するヘッドレストガイド7には、牽引バネ25を介してシート側コネクタ20を上下自在に設け、牽引バネ25の弾力はシート側コネクタ20のシート側金属端子22とピラー側コネクタ10のピラー側金属端子11とが嵌合するより強くシート側コネクタ20を上動するように構成しているから、ヘッドレストガイド7にピラー8を挿入すると、ピラー8のピラー側金属端子11はシート側コネクタ20のシート側金属端子22に嵌合し、ヘッドレスト内接続コード6と給電用コード23とは接続状態となる。 The headrest guide 7 for mounting the pillar 8 of headrest 3 is provided with a seat-side connector 20 to freely vertically via a traction spring 25, the seat-side metallic terminal 22 and the pillar-side connector elasticity of the traction spring 25 seat-side connector 20 since 10 and pillar-side metal terminal 11 is configured to move upward the more strongly seat-side connector 20 is fitted, when the headrest guide 7 to insert the pillar 8, the pillar-side metal terminal 11 of the pillar 8 sheets fitted to the seat-side metallic terminal 22 side connector 20, a connection is established between the headrest in connection cord 6 and the power supply cord 23.

この状態で、ヘッドレスト3を所定位置まで下げると、これに応じてピラー8はシート側コネクタ20を下方に押し下げ、ピラー8の下端がヘッドレストガイド7の下端より下方に位置すると、ピラー8の外周にシート側コネクタ20の絶縁上下移動体21が牽引バネ25の弾力により当接したままとなって、ピラー側コネクタ10とシート側コネクタ20は接続状態を維持する。 In this state, lowering the headrest 3 to a predetermined position, the pillar 8 is pushed down the seat-side connector 20 downwardly in response thereto, the lower end of the pillar 8 is positioned below the lower end of the headrest guide 7, on the outer periphery of the pillar 8 insulator vertical mover 21 of the seat-side connector 20 becomes kept in contact by the elasticity of the traction spring 25, the pillar-side connector 10 and the seat-side connector 20 maintains the connected state.

また、ヘッドレスト3を上動させると、ピラー8が上動し、シート側コネクタ20は牽引バネ25により上方に牽引されるから、シート側コネクタ20はピラー8に追随して上動する。 Moreover, when moved upward the headrest 3, the pillar 8 is moved up, because the seat-side connector 20 is pulled upward by the traction spring 25, the seat-side connector 20 is moved upward following the pillar 8.
したがって、電気部品5を設けたヘッドレスト3であっても、上下調節可能となる。 Therefore, even in the headrest 3 provided with the electrical components 5, it enables vertical adjustment.

(脱着) (Desorption)
ピラー側コネクタ10とシート側コネクタ20が接続された状態で、ヘッドレスト3を上動させ、ピラー8の下端がヘッドレストガイド7の下端より上方に位置すると、シート側コネクタ20の絶縁上下移動体21はヘッドレストガイド7の下端に当接して上動が阻止されるから、この状態で、更にピラー8を上動させると、シート側コネクタ20はヘッドレストガイド7の下端に当接したままとなって、ピラー8のピラー側コネクタ10のピラー側金属端子11はシート側コネクタ20のシート側金属端子22より外れる。 In a state in which the pillar-side connector 10 and the seat-side connector 20 is connected, the headrest 3 is moved upward, the lower end of the pillar 8 is positioned above the lower end of the headrest guide 7, an insulating vertical mover 21 of the seat-side connector 20 since upward movement is prevented by contact with the lower end of the headrest guide 7, in this state, when the further upward pillar 8, the seat-side connector 20 is kept in contact with the lower end of the headrest guide 7, the pillar pillar side metal terminal 11 of the 8 pillar-side connector 10 of the outside than the seat-side metallic terminal 22 of the seat-side connector 20.

したがって、何の接続解除作業(操作)をすることなく、単に通常のヘッドレスト3の取り外し作業を行うことで、ヘッドレスト3を外せる。 Thus, without any connection release operation (operation), merely by performing the removal operation of the conventional headrest 3, Hazuseru headrest 3.
また、前記したように、ピラー8をヘッドレストガイド7に挿入するだけで、何の接続解除作業(操作)をすることなく、ヘッドレスト3の取付けができ、それゆえ、電気部品5を有するヘッドレスト3でありながら、特別な接続作業をすることなく、ヘッドレスト3の「脱着」が行える。 Further, as described above, the pillar 8 by simply inserting the headrest guide 7, no connection release operation (operation) without the attachment of the headrest 3 can be, therefore, at the headrest 3 having electrical components 5 There will, without a special connection work, can be performed "desorption" of the headrest 3.

(導通性能) (Conduction performance)
電気部品5への給電は、ピラー側コネクタ10とシート側コネクタ20を介してヘッドレスト内接続コード6および給電用コード23により行われるから、ヘッドレスト内接続コード6および給電用コード23による導通性能が十分に発揮され、導通性能を低下させることを防止する。 Power supply to the electrical components 5, since is performed by a headrest in connection cord 6 and power supply cord 23 through the pillar-side connector 10 and the seat-side connector 20, electrical conduction is sufficiently by the headrest in connection cord 6 and power supply cord 23 It is exerted to prevent the lowering conduction performance.
